- 1?) aZZ wit-0m it may comer n .,]Be it, known, that I. Elwin DAVIES, a citizen of the. United- States, residing'at Salt -htate o l -Utalnhave invented a new and nset'ul Attachment for l'lydrocal'bon llngines,

of: which thetollowing is a specitica, ion. This inventionrelatesto an attachment tim .hydrocarbon engineswhereby a mixture of air and water can be supplied in desired v quantitiesto the gasemis fuel lmingsupplied to.an engineto increase the ell'ici ency of the fuel a;1 l eii ect a considerable saving in the I e to provide an attach incl; eanbe applied readily to an which is cheap to nianutactnre, can

engine be cleaned readily, and is constantly under the control of the operator. With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment oi the invention herein disclosed. can be made within the scope ofwhat is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention basbeen shown.

In said-drawings: Figure is a plan View of the attack ment.

Fig. 2 is a section on line 2*2 of Fig. 1. Fig. 3 is a plan view of the revolnble body of the attachment-,the cap being removed.

Fig. 4 is an inverted plan view of the cap. Referring to the figures by characters of reference 1 designates a stationary cap in the form of a disk having a central screw threaded stem 2 for engaging a supporting structure. A radialarin 3 is formed on the disk or cap and is provided with a laterally extending inlet porte opening into the passage 5 which extends through the arm 3 and has an outlet port 6 opening through the bottom of the cap. A needle valve 7 is mounted in the arm 3 so as to control the flow of Water from the port 5 to the passage in the arm 3.- v

An aperture 8 is formed in the cap 1 and Lake City. in thacounW of Salt Lake and ATTACHMENT FOR HYDROCARBON-ENGINES.

extends entirely through it front top to bottom. 7

Extending from the center of the cap I is a tubular stem 9 on which a hollow cylindrical body 10 lSJHOilfltGd for rotation, this body being provided in its ends with openings 11 through which the. Stein. 9 pro je -ts. That portion of the stem housed within the body 10 is provided with small apertures 12 communicating with the interior of the body. The free end portion of the stem 5) is screw threaded as at 13 for engagement with the manifold of an engine at a point between the earbureter and the inlet valve. A spring 14 is mounted on the stem and bears at oneend against the body 10 and at its other end against a washer 15 which is detachably mounted on thesteni, being held in place by a pin 16. This spring serves to hold the body pressed tightly against the'cap l. Formed in the body are spaced openings 17 and 18. When the opening 17 is in register with the port 6 the opening 18' is in mg ister with the aperture 8. lVhen the body 10 is turned upon the stem 9 communication between theepenings in the bodyand the ports 6 and 8 "will be simultaneously;reduced or out otf as desired.

For limiting the relative movement of the body 10 and cap 1 spaced ears 19 areoX- shown particularly in Figs. 1 and The.

cap 1 has a single car 20 provided with a depending pin 21. This pin projects between the ears l9. and, by engagement thereby. limits the movement of the body.

An arm 22 is extended radially from the body 10 and may be connected to an actuating rod or the like. not shown, whereby the body 10 can be rotated readily.

As before poi uted out the threaded end 13 of the stem 9 is to be attached to the manifold between the carbureter and the inlet valve. The port at is adapted to be placed in communication with the radiator or some other source of water supply. By means 0f the said body. The suction created by the encan be readily removed and cleaned, it

merely being necessary to remove the'pin 16 in order tQ PQI'IHIiJ'SGPaI'HtlOII of the parts.

4 What is claimed is 1. An ai'r moistening attachment for hydrocarbon engines including .astationary member having air and water ports therein, valved 'means for controlling the flow of water to the Water port, a tubular stem extending from said stationary member and open at one end, a hollow member mounted for rotation Ion the stem and having ports movable into and out, of register with the respective ports in the stationary member, there being outlet openings within the stem and communication with the interior of the movable 7 member',' and cooperating means. upon the members for limiting their relative movement.

. 2. An air moistening attachment for hydrocarbon engines including a tubular stem for attachment to the manifold of an engine,

a cap carried by this stem and having an;

. and .water ports trolling the supply of water to the water ports, said stem having an apertured portion, a hollow body mounted for rotation upon the apertured portion of the stem and spaced ports,- means for shifting said body to shift the ports simultaneously; into or out of register with the respective ports in the stationary member, and resilient means for holding the two members pressed together.

3. An air moistening attachment for hydrocarbon engines including a tubular stem for attachment to the manifold of an engine, a cap carried .by this stem and having air and water ports therein, a valve for controlling the supply of waten. to the water ports, said stem having tion, a hollow body mounted for rotation an apertured por-' therein, a valve for con-' upon the apertured portion of the stem and spaced ports, means for shifting said body to shift the ports simultaneously into or out of register with the respective ports in the stationary member, and resilient means for holding the two members pressed together, and cooperating means-uponthe two members for limiting their relative movement. In testimony that I, claim the foregoing ;as my own, I have hereto afiixed my signature in the presence of two witnesses. 7 DAVID DAVIES.
